Eyebrows, LED front side markers, and new LED tails that tie into the X1, Z4, E90, F01, and upcomming 5er design schemes. The side skirts look different too, although it maybe just the shot, or shadow. Same crap truckster/SUV mirrors they slapped on the LCI E90. Thanfully they aren't as big as the Benz C-Class mirrors...It was only a matter of time.
This facelift is pretty much the same as the LCI E90 minus the hood. I too wonder if they widened the track a bit. I'm sure it will look nice in person like the LCI E90 did, minus the mirrors, and 4X4 status...
